Laser pointers (toys and stuff for conferences etc) are much smaller powered maximum 5mW so 50times less than this bad project...often they are under 1mW real power.
Watching at them could give damages too... but cause of small power it requires more time to make real damages to retina... that's a live tissue and could also partially regenerate a very small burnt.

Laser pointers are supposed to give you time to blink, before damaging your eye.
LASERS ARE NOT TOYS, AND YOU SHOULD NOT "PLAY" WITH ANY LASER, THIS APPLIES TO LOW POWER LASER POINTERS. IT IS POSSIBLE TO EXPERIMENT SAFELY WITH HIGHER POWER LASERS, BUT MAKING ONE INTO A LASER POINTER, AS THE GUY IN THE VIDEO DID, IS JUST PLAIN
STUPID.
